FACT(s) (Environment):

Progress 9.x
OpenEdge 10.x
WebSpeed 3.x

SYMPTOM(s):

WebSpeed agents stay busy when calling _help.r with no parameter

Using messenger URL ending with _help.r with no additional parameters in the query string

Sample URL
http://host/scripts/cgiip.exe/WService=wsbroker1/_help.r

Remote denial of service attack is possible against WebSpeed when such crafted URL is used

Issue occurs also when deploying in "Production" mode

CAUSE:

This is a known issue being investigated by development

FIX:

The recommended immediate workaround is to rename $DLC/src/_help.p, $DLC/tty/_help.r and $DLC/gui/help.r.
Network administrators should also set up the web server to log any attempts to access URLs ending with help.r / help.p.
